IT Assignment

Question: Further background: Youth assigned to a headspace case worker may subsequently be admitted to the Emergency Department (ED) of the local regional hospital. Currently there is no requirement for the ED staff to notify the headspace case worker when a client has been released. Sometimes case workers are notified, but often not. It means that days and even weeks can transpire before a case worker becomes aware of that release. In the meantime the young person tends to return to the environment and circles of influence that led to the suicidal behaviours in the first place, without the coping and support mechanisms that a case worker can provide. Consider that funding has been approved for a project to build a system that will capture the ‘story’ the first time it is told, and give access to successive professionals, so that case notes and the story can become enriched, and the young person can be assisted more appropriately. You are business systems analyst assigned to the project, you will need to produce:

•  A draft Project Vision.

This sets out the business case, and summarises other aspects of the project, including ‘needs and features’, and other product requirements.

•  Functional Requirements Specification.

This should involve a Use Case Model, backed up by short use case descriptions. There should be at least one full use case description for a critical core use case; this could be an Emergency Department admission, or inter-agency communication, such as between a public hospital psychiatrist and a headspace case worker. (Identifying critical core use cases allows us to address the issue of project risk).
